Gas Control System


Independent control of blood gases
  • Targeting of PCO2 and PO2 is independent of each other
  • Range of PCO2 targeting: 25 – 70 mmHg
  • Range of PO2 targeting: 70 – 700 mmHg*. PO2 as low as 40mmHg can be achieved if required

Choose from multiple blood gas targeting patterns that are built-in:

  • Box car
  • Continuous Ramp
  • Sinusoidal
  • Combination of above
  • Accuracy within 2 mmHg of target for PCO2
  • Transitions in PCO2 and PO2 can often be achieved in 1-3 breathes, under many circumstances within 1 breath

Required Gases
The following gas mixtures are required:

  • Gas A: 10% O2, 90% N2
  • Gas B: 10% O2, 90% CO2
  • Gas C: 100% O2
  • Calibration Gas: 10% O2, 9% CO2, 81% N2

We suggest that you order K size cylinders for Gas A, B and C and a E size cylinder for Calibration gas. If the “wall Oxygen” is available, it can replace the Gas C. Secure cylinders as per your local regulations.
